I claim as my invention-- 1. A settling device for filtering, comprising a tank in which are provided a number of compartments, through which the liquid flows successively, and screens located near the bottom of said compartments, over which the liquid flows, substantially as described.

2. A settling device for filtering, comprising a tank in which are provided a number of partitionwalls to form compartments, through which theliquid flows successively, a screen located near the bottom of each compartment, so as to have a space below it in which impurities are held, a partition-board in each compartment adjacent the partitionwall to form a passage, and a deflector-board at the end of the passage so formed, whereby the water will fiow from one compartment through said passage and over the screen, substantially as described.

3. A settling device for filtering, comprising a tank in which are provided a number of compartments through which water flows successively, each of said compartments being provided with a channel-bottom, screens located above each of said bottoms, suitable means for flushing said compartments and suitable means for effecting a discharge from the bottom of each of said compartments, substantially as described.

4-. A settling device for filtering, comprising a tank in which are provided, a number of compartments through which Water flows successively, each of said compartments being provided with a channel-bottom and a curved end, suitable means for flushing said compartments, and suitable means forelfecting a discharge from the bottom of each compartment, substantially as described.

5. A settling device for filtering, comprising atank having a number of compartments, a top for said tank composed of I-beams B, hollow tiles between some of the beams and located over some of the compartments, and glass plates or lenses between the other beams and over the other compartments whereby the action of the suns rays may be had on the liquid in such compartments,substantially as described.

6. A settling device for filtering, comprising successive compartments of varying size and a screen located near the bottom of each compartment so as to have a space below it in which impurities may settle, substantially as described.

In testimony whereof I have signed my I name to this specification in the presence of two subscribing witnesses.
